USN-3132-1: tar vulnerability

Releases

• Ubuntu 16.10
• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• tar - GNU version of the tar archiving utility

Details

Harry Sintonen discovered that tar incorrectly handled extracting files
when path names are specified on the command line. If a user or automated
system were tricked into processing a specially crafted archive, an
attacker could possibly overwrite arbitrary files.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.10

• tar - 1.29b-1ubuntu0.1

Ubuntu 16.04

• tar - 1.28-2.1ubuntu0.1

Ubuntu 14.04

• tar - 1.27.1-1ubuntu0.1

Ubuntu 12.04

• tar - 1.26-4ubuntu1.1

In general, a standard system update will make all the necessary changes.
